What gives? The output of sudo modprobe -vvv xpad is: modprobe: INFO. However, sudo modprobe xpad yields modprobe: ERROR: could not insert 'xpad': Operation not permitted. Using some hints posted here, I got a copy of xpad.c for my kernel (4.18.0), edited xpad.c to add some lines for my controller's ID (0e6f:02c6), and compiled and installed the module. As is, my Ubuntu 18.10 system doesn't seem to recognize it its power light doesn't even turn on. I'm trying to use a new PDP Xbox One controller ('Crimson Red').
